6 Replies and 1901 Views View Display Settings  1901  6 Started by  chad.grant Because of the i.MX31 end of life we are trying to move to the DM3730 SOM-LV. On the i.MX31 we used 'video-init 5 16', and those default settings worked great. No such luck with the DM3730, 'video-init 5 16' is close because I can see some of the right colors, but there is a lot of flicker and shadows. I can use 'info video 5' command on the DM3730 (runnig LogicLoader 2.5.2) and I get: Name:           LQ036Q1DA01 Number:         3 Resolution: &nb...

8 Replies and 2108 Views Ethernet packet storm overloads CPU processor  2108  8 Started by  Gary Baran Our product which utilizes the MIMX31BSOMCR SOM will cease to function if the ethernet connection receives a broadcast or multicast packet storm. It would appear that the CPU becomes overloaded. This happens in both Lolo and also while running a WinCE 5.0 image. Is there any resolve for this issue

1 Replies and 2391 Views Are i.MX31 Sources Available?  2391  1 Started by  Deleted User Hello, We use the i.MX31 processor and need to make some changes to the vfp library settings. It must be IEEE-754 compliant and must generate the same results as 'normal' windows pc's for all kind of functions like Sin, cos, tan, exp, log. Problems is that it seems that this setting must be changed in code and the library (most likely called 'vfp loader' must be re-compiled. Are these sources available or is it possible to change the compliance settings without re-compiling the bsp ...

0 Replies and 1606 Views MC13783 watchdog reset  1606  0 Started by  rishid I am trying to use the external reset function of the IMX31 watchdog in combination with the MC13783 PMIC. I have been able to get the PMIC to trigger the system reset line low when the IMX watchdog times out. The problem I am having is the PMIC never releases the reset line to actually reset the entire system. Anyone know how to get the PMIC to automatically restart the system when the WDI line goes low

I have been getting 2.6.38-rc2 going and its working well. but, when I try to talk to the MBX chip I get nothing. the only code I have found so far relevant is the mapping of the Peripheral remap register. once I applied that code I now get different results from my reading of the registers. but not the expected results, I believe there is some platfor...

We have seen a number of these fail after 10 months in the field with what appears to be a corrupt yaffs partition.

Doing an add-yaffs works, but when a mount is tried, the SOM hangs. Anybody seen something like this I've been trying to get LogicPDs attent...

From microsoft (http://msdn.microsoft.com/en-us/library/ms939597.aspx) I see that the value dwNKDrWatsonSize needs to be set in the OEMInit function so that memory will be reserved for error reporting. The only problem is that I can't find the source code for OEMInit in the platform code. I hoped that the value would already be set, but when I built the image none of the error reporting features...
